    Re-download the installer. Be sure you are using a fast internet service.

    Yes, it is high speed internet access. Ran the below and installer is being re-download now.  thanks.

     

    Run the following command in Terminal:

    open $TMPDIR../C/

     

    a folder will open in the Finder showing a number of cache folders for different applications. Delete the com.apple.appstore folder, then quit and relaunch the App Store application and try the download again.
